mo.Button Wiring Diagram & Troubleshooting

We receive more inquiries for support of this product from own customers as well as everyone else than any other issue hands down. So we’ve created this diagram and a definitive guide for installing the mo.Button. What follows is everything we know about it and the entirety of the technical support that we are able to provide for it. There are many ways to go about it but there is only one recommended way that can be found in a single bold line in section 8.8 of the m-Unit manual version 2.3.

Motogadget has its own support team that can be reached via their website through the link below. If you have a bad Motogadget product that is under warranty and requires replacement it must be returned directly to Motogadget for exchange, dealers no longer handle warranty exchanges or returns. Please see the link below for details.

First things First, Download the most current version of the manual for your m-Unit. It is updated regularly and you can find the newest versions here. For specific issues use your CTRL+F search function with simple terms to locate specifics.

THE M.BUTTON MUST BE LOCATED INSIDE A METAL HANDLEBAR TUBE.

There is a good reason for this if you choose to deviate from that instruction all bets are off. The handlebars act as an RFI shield for the mo.Button. The mo.Button is a Digital CAN-BUS device and the signals it sends to the m-Unit are susceptible to Radio Frequency Interference (RFI) which most motorcycle ignition systems emit to some degree or another.

Proper Handlebar Installation:

Pre-drill holes for internal bar wiring, with one hole at the bottom center. Be sure to clean up edges to avoid wire chafing, we recommend using wire loom to protect the tiny wires.
Run left side control wires from the right bar end.
Run Green wire and mo.Button Black ground to the center hole.
Insert mo.Button in the right bar end.
Feed right side control wires through the hole.
Feed all left and right side ground wires through bars to the center hole. Solder all ground wires to mo.Button main ground and run one ground wire back to the m-Unit main ground terminal to ensure the best continuity.

mo.Button Troubleshooting

Problems with the mo.button tend to manifest in one of two ways:

1. One or more control functions not responding

This could be the result of a bad switch, bad wire connection, or an irreparable internal failure in the mo.Button. Due to the mo.Buttons digital CAN-BUS technology, you can not test for continuity in your switches. In order to test a switch or its circuit to determine if the switch is bad, there’s a wiring issue or the mo.Button is malfunctioning you must perform a process of elimination.

A. Test for continuity between the switch and the mo.Button, check wiring for damage.
B.Test switch for continuity when pressed.
C. If the above tests are good it is an indication that there is an issue with the mo.Button.

2. Phantom switch activations

The most common issue that we encounter is the result of improper installation. If you have an mo.Button and are experiencing phantom switch activations this is very likely due to electromagnetic interference. If your mo.Button is not as stated in the manual, inside the handlebars this is a probable cause for your issues. Proper installation may solve the issue, then again, if your ignition system if throwing off enough EMI it may not be enough. If you are still experiencing symptoms you may need to confirm that you are using either suppressor core wires or suppressor plug caps and if you are still experiencing these symptoms removal of the mo.Button is the most prudent solution.
